Spearhead made a joyful splash when it arrived on the craft brewing scene last year. Its motto, “beer without boundaries,” testifies to an experimental philosophy. The Moroccan Brown Ale, for example, is flavoured with dates, figs, raisins and cinnamon. And this superb Hawaiian ale gets its twist from pineapple. The fruit is subtle, though, a perfect counterpoint to the dry-hopped citrus- and pine-like bitterness, like a Pacific island planted with Christmas trees.
